中国大陆地区GNSS对流层延迟与PM2.5浓度的相关性研究
Correlation Analysis of GNSS ZTD and PM2.5 Concentration in China
摘要
Abstract
According to the high correlation between GNSS zenith tropospheric delay (ZTD) and precipitable water vapor (PWV),the Crustal Movement Observation Network of China (CMONOC) is taken as an example to study the correlation between GNSS ZTD and PM2.5 concentration in China.Based on the comparisons of GNSS ZTD and PM2.5 concentrations from December 2015 to February 2016,it is found that there are positive correlations between GNSS ZTD and PM2.5 concentration in Northeast China,North China,Central China,part of Northwest China and part of Southwest China.While there are negative correlations in east China and south China,part of northwest China and southwest China.According to the analysis of precipitation and wind velocity during the same period,it was found that precipitation and wind velocity are shown significant influence on the correlation between GNSS ZTD and PM2.5 concentration.In the regions of positive correlation of GNSS ZTD and PM2.5 concentration,the change of GNSS ZTD is positively corresponding to the change of PM2.5 concentration.关键词
